Electron micrograph of a nerve from the mesentery of a rat shows groups of unmyelinated axons wrapped by deeply invaginating Schwann cells in cross section. Surrounding the Schwann cell wrapping is a ...

Sarcolemma of skeletal muscle prepared by a quick-freeze deep-etch method also shows the basement membrane (lamina externa, labeled here as the basal lamina) associated with the muscle fiber. This me...

Two electron micrographs of smooth muscle cells in a small artery, surrounded by a light gray zone of interspaces composed of an elastic fiber and collagen-rich basement membrane. The elastica intern...

Quick-frozen deep-etched preparation of skeletal muscle tissue shows the muscle fiber and associated extracellular components. The basement membrane (labeled basal lamina) lies adjacent to the undulat...

The image shows an anchor cell (red) in the developing female reproductive system of C. elegans pushing through the basement membrane (green) that surrounds it. This type of invasion is also often see...

Colocalization of the microtubule anchoring factor LL5α (red) with integrin α6 (blue) in the basal cortex of outer epithelium of mouse mammary gland tissue, and laminin (green) in the basement membr...

Colocalization of the microtubule anchoring factor LL5α (red) with integrin α6 (blue) and laminin (green) in the epithelium of mouse small intestine. LL5α is localized to the basal cell cortex atta...

Schwann cells in peripheral nerves secrete a layer similar to the basal lamina called the lamina externa, boundary layer, or basement membrane. In this micrograph, the lamina externa surrounds the Sc...

Transmission electron micrograph of a tangential section of a rat glomerulus basement membrane. The series of images in this group have particular historic and cell biologic importance for determini...

Transmission electron micrograph of rat kidney filtration barrier. Micrograph illustrates the basement membrane between fenestrated capillary endothelium and podocyte foot processes at intermediate m...
